What I'm looking for

I'm looking to build secure, scalable web and payment platforms where I can solve integration challenges, improve performance, and deliver reliable customer-facing systems.

At Riverbank Solutions, I build secure ETL pipelines and payment integrations across REPAY, CyberSource, Authorize.Net, Centricity, VCI, and Accept Blue. I created reconciliation workflows and a .NET MVC reporting portal, reducing processing time by 40% while improving data accuracy.

Previously at Corebase Solutions, I developed backend services for online sales and POS systems supporting 10,000+ concurrent users and reducing response times by 50%. Across healthcare, school, and financial systems, I've delivered .NET, C#, API, database, reporting, and mobile solutions that connect payments, inventory, tax compliance, and customer workflows.
